In simple words, the total mass of a chemical element in the unit number of moles is generally represented by molar mass. In the SI (International standard) unit, the molar mass is represented by gram per mole. For example, the molar mass of the Carbon monoxide ...
displays. Determining the number of moles is not as straightforward. In the case of a gaseous sample, knowing its pressure and volume at a specific temperature provides enough information to determine the number of moles present. Using the mass and number of moles, the molar mass can be determ...
This report gives accurate interpolation functions for the Clausius-Mossotti functions (molar polarizabilities) of pure compressed gaseous and liquid methane, ethane, propane, butanes and nitrogen; and suggests a method for calculating the dielectric constants or the densities of their mixtures. The ...
A mixture of gases has the following composition by mass. CO2 = 19.3% O2 = 6.5% H2O = 2.1% N2 = 72.1% What is the average molecular weight of the gaseous mixture? A gas mixture contains 40 moles CO, 25 moles CH4, and 80 mo...
Apparent molar volumes of all solutes were calculated in the usual way resorting to Eq. (1).Vφ,B={(ρ0-ρ)/(mBρρA∗)}+MB/ρ,where MB represents the solute molar mass, mB the molality of the solution and ρ and ρA∗ the densities of the solution and solvent, respectively....
From the standard molar enthalpies of formation of the gaseous complexes, the mean molar (Cu-O) bond-dissociation enthalpies were derived.doi:10.1006/jcht.1995.0014Manuel A. V. Ribeiro da SilvaManuel J. S. MonteJan HuininkJournal of Chemical Thermodynamics...
